Rose plant named &#39;RNF Yellow 01&#39;

ABSTRACT

A new and distinct rose plant having a strong fragrance and creamy yellow-colored flowers.

Botanical classification: Rosa L.

Varietal denomination: ‘RNF Yellow 01’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of rose plant known by the varietal name ‘RNF Yellow 01’. The new variety was discovered in April of 2010 in Gifu, Japan. The new variety is the result of a planned breeding program between Rosa L. variety ‘Gold Bunny’ (female parent, U.S. Plant Pat. No. 4,625) and an unnamed and unpatented Rosa Rugosa variety (male parent) from the breeder's own collection. ‘RNF Yellow 01’ has a different flower color than its female parent. Additionally, ‘RNF Yellow 01’ exhibits a fragrance like its male parent, but differs from its male parent in its actual fragrance. When ‘RNF Yellow 01’ is compared to Rosa L. ‘JAChal’ (U.S. Plant Pat. No. 11,883, Japanese Patent No. 13281), the varieties are similar in flower color, not having eyes on their flowers, and in that they exhibit double flowers. However, when compared to ‘JAChal’, ‘RNF Yellow 01’ has a larger flower size, different number of petals, and exhibits a fragrance. When generally compared to other rose varieties known to the breeder, the new variety differs in its strong fragrance, its type of fragrance, and in flower color. ‘RNF Yellow 01’ has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, with the color being as nearly true as is possible with color illustrations of this type:

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which defines these characteristics were collected by asexual reproductions first performed via cuttings in May of 2011 carried out in Gifu, Japan. Plants of the new variety were grown in a greenhouse under natural light in 15 cm pots with peat moss substrate and with the assistance of heaters in the winter. The color readings and measurements were taken indoors in a greenhouse under natural light on one year old plants grown in containers. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London.
